Breeding and Characteristics of New Early-maturing and High-yield Late Geng Rice Variety Changnonggeng No.2
摘要
Abstract
To provide excellent geng rice varieties for the late rice planting areas in Hubei Province,Yangtze University,in collaboration with the Institute of Crop Science of the Chinese Academy of Agricultural Sciences,took the self-bred variety Changnonggeng No.1 as the recipient parent and the early-maturing rice blast-resistant germplasm resource VE6219 as the donor parent to breed the new early-maturing and high-yield late geng rice variety Changnonggeng No.2 by the pedigree method.The whole growth period of this variety is 7.2 days earlier than that of the control Ewan 17,and the yield is 8.20%higher than that of Ewan 17,showing the characteristics of early maturity and high yield.The variety was approved by Hubei Province in 2022,with the approval number of Eshendao 20220036,which is suitable for planting as late rice in the rice blast-free areas or light disease areas of the double-cropping rice areas in Hubei Province.This paper introduces the breeding process,characteristics and key cultivation techniques of Changnonggeng No.2,in order to provide technical support for the promotion of Changnonggeng No.2.关键词
